Siblings in KEF's Q Meta series, so they share a family sound. It comes down to size, output and price.
| Area | Better | Why |
|---|
| Bass |
B |
KEF Q7 Meta digs deeper - 46Hz against 105Hz. |
| Amplifier needs |
evenly matched |
Similar sensitivity (86dB vs 87dB) - both want much the same power. |
| Size |
depends |
KEF Q8 Meta is easier to place; KEF Q7 Meta is bigger, which usually goes with fuller bass. Your room decides. |
| Type |
depends |
A Passive Surround against a Passive Floor-standing - a different job rather than a better one. |
| Cabinet |
depends |
Sealed vs Ported. Sealed is tighter and happier near a wall; ported digs lower but wants space behind it. |
| Price |
A |
KEF Q8 Meta is cheaper - $900 against $1,800, about 50% less; arguably a different class. |

depends neither is better in the abstract - it turns on your room, placement or how you will use them.
Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
KEF Q7 Meta is ahead, but only on 1 of the measured areas, and it costs about 50% more. That is a lot of money for a narrow margin on paper - KEF Q8 Meta looks like the sensible buy unless something else about the KEF Q7 Meta appeals to you. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 105Hz anyway, which makes the cheaper KEF Q8 Meta much easier to justify. In a large or open-plan room, KEF Q7 Meta has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, KEF Q8 Meta is the easier speaker to get right.
And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
